Abstract: ABSTRACT OF THE DISCLOSURE       Disclosed is an AC elevator control apparatus, in which AC power supplied from an AC source is rectified by a converter and a smoothing capacitor into DC power, the DC power being in turn converted by an inverter into variable-frequency AC power by which an AC electric motor is driven to operate an elevator cage.  The apparatus includes a rectifying circuit connected to the AC source, a resistor connected between the rectifying circuit and the smoothing capacitor, a charging time measuring circuit for measuring the time from turn-on of the AC source until the completion of charging the smoothing capacitor, and a control circuit for producing an abonrmality detection signal when it is detected that the output of the charging time measuring circuit is shorter than a predetermined value, whereby the reduction in capacitance of the capacitor, and hence the expiration of the lifetime of the same, can be evaluated in advance.

Abstract: ABSTRACT   A method and apparatus is disclosed for refining lignocellulose containing material in which a gaseous medium is present.  In accordance with this method and apparatus, the lignocellulose material is refined between a pair of opposed inner and outer refining surfaces by rotating the refining surfaces in opposite directions along a common axis.  Gaseous flow paths are provided along the inner refining surface to provide for sufficiently uniform gaseous flow therealong during refining to avoid a stoppage of gaseous flow to an extent which would result in deleteriously affecting the material being treated.  The refining surfaces are angularly disposed relative to the common axis such that, during refining, the material being treated is urged by centrifugal force against the outer refining surface to affect simultaneously the desired refining of the material and the flow of gaseous medium along the flow paths to avoid deleteriously affecting the material.

Abstract: ABSTRACT       The invention relates to a scanning device for reading and/or writing using a laser beam. A drum (243) includes a rotatable shaft (102) carrying optical elements (120) which are moved rotationally and translationally to cause a laser beam to scan sheet material lying around the surface of a cylinder coaxial with the shaft. A sheet to be scanned is placed on a flexible transport (150) while flat and then the transport is fed into the drum until a surface of the transport is in intimate contact with a location wall (243) of the drum. A bed (191) supports the flat transport outside the drum and there is a support (211,212) for supporting a transport above the bed together with positioning means (200) for the bed and support either for driving a transport on the bed into the drum or for driving a transport in the drum onto the support. The shaft (102) is rotatable in a housing (101) on air journal bearings (100) and end thrusts are balanced by air thrust bearings defined between a wall (125) of a reaction air turbine for driving the shaft, and a wall (124) of a porous plate through which air for the bearing is supplied through a controllable restriction (1232,1233).

Abstract: ABSTRACT     A switching system for performing line to line or group to group switching of communication signals modulated by multiplexed noise codes.  The noise codes comprise a subclass or set of multiplexed noise codes consisting of code mate pairs which provide an impulse autocorrelation function when detected and furthermore crosscorrelate to zero at a time when the code mate pairs compress to an impulse providing thereby orthogonal operation, meaning that there is no mutual interference between any of the input/output lines when the signals are translated thereon concurrently. Plural sets of noise code generators and code selectors are coupled to predetermined ones of a plurality of sets of matched filter detectors and code selectors in accordance with a switching algorithm which sets selected code selectors to the same code mate pairs so that a specific signal applied to a predetermined input line and thereafter coupled to modulation means connected to one set of code generators is directed to a predetermined output line that is connected to a matched filter decoder pair matched to the input code.

Abstract: ABSTRACT OF THE DISCLOSURE:           A device for arranging fish in uniform head-tail alignment comprises a rotating gripping device of radially arranged pincer-like gripping elements.  These form a vertical slot into which the fish led tail end first are introduced. Following the rotation of the gripping device the gripping elements are held closed in a region of a stationary sector of each one revolution so that the tail fin is grasped and the fish carried along thereby.  After passing the highest point of the revolution of the gripping device the fish turns over under the effect of gravity and is then released head end leading.  Fish led head first cannot enter the slot because of their thicker heads and are passed on directly.

Granted: 1989-06-06
Abstract: MPO848-US2/4631 A single-phase ground enclosed load break switch for distribution voltages has a hermetically sealed cylindrical metal housing of from 2 to 6 inches diameter which contains an insulating gas under pressure. The switch has a movable contact assembly to contact a pair of opposed stationary coaxial conductors within the housing. Movement of the contact assembly along one conductor breaks the connection with the other conductor and simultaneously reduces the sliding contact force on the first conductor. The switch has conductive bands coaxially positioned near the housing around the conductors for low voltage measurements monitoring conductor energization and contact position. A rocking bellows at the fulcrum of a crank actuator provides a compact hermetic seal for the actuator without excessive strain of the bellows. A safety interlock with a visual indicator locks the contact assembly in case of a loss of pressure. Excessive pressure in the switch causes the bellows to be punctured with consequent locking of the contact assembly. The switch is small enough to be mounted directly on a transformer or placed into a cable, without the need for a separate enclosure.
